Unfortunately, mvebu-audio has already been taken by Mark. Also, we
know the differences for the three SoCs now and should have a compatible
for each (and maybe mvebu-audio for fallback).
Also, we'll need to distinguish between the different audio controllers
on a single SoC, i.e. i2s0 and i2s1. I suggest checking the (phys) reg
base passed.
